Description
本發明是有關於一種塑膠材料、光學成像鏡頭及取像裝置，且特別是有關於一種可吸收短波長的塑膠材料、以及一種可吸收短波長光線並可應用在電子裝置上的小型化光學成像鏡頭及取像裝置。 The present invention relates to a plastic material, an optical imaging lens and an imaging device, and more particularly to a plastic material that can absorb short-wavelength light, and a miniaturized optical imaging that can absorb short-wavelength light and can be applied to electronic devices Lens and imaging device.
近年來，搭載於行動產品的微型攝影鏡頭蓬勃發展，微型攝影鏡頭內部配置的光學鏡片皆採用塑膠材質，藉以滿足微型化、非球面製造與量產的需求。 In recent years, miniature camera lenses mounted in mobile products have flourished. The optical lenses inside the miniature camera lenses are all made of plastic materials to meet the needs of miniaturization, aspherical manufacturing, and mass production.
然而，當光學鏡片以塑膠材質製成，其無法有效對抗短波長光線如紫外光或高能量藍光的損害，因而可能產生塑膠光學鏡片劣化的問題，進而導致攝影鏡頭的耐用度與成像品質皆下降。 However, when the optical lens is made of plastic material, it cannot effectively resist the damage of short-wavelength light such as ultraviolet light or high-energy blue light. As a result, the deterioration of the plastic optical lens may occur, and the durability and image quality of the photographic lens will decrease. .
為解決上述問題，遂有業者發展出鏡片鍍膜技術，其係於光學鏡片上鍍上一層或多層可反射紫外光的膜層。藉此，雖可有效降低紫外光對塑膠光學鏡片的損害，然 而，於微型光學鏡片上鍍膜的成本較高，且均勻完美的鏡片鍍膜技術困難性過高，不利於提升良率。 In order to solve the above problems, some industry has developed lens coating technology, which is to coat optical lenses with one or more layers that can reflect ultraviolet light. In this way, although UV light can effectively reduce the damage of plastic optical lenses, the cost of coating on micro-optical lenses is relatively high, and the technical difficulty of uniform and perfect lens coating is too high, which is not conducive to improving the yield.
因此，相關業者仍企求一種塑膠光學鏡片，其可有效消除短波長光線，藉以提升攝影鏡頭的耐用度與成像品質，且可有利於攝影鏡頭的微型化，從而有利於搭載於行動產品，並可避免鏡片鍍膜技術製造成本過高與技術難度過高的缺失。 Therefore, the related industry is still looking for a plastic optical lens that can effectively eliminate short-wavelength light, thereby improving the durability and imaging quality of the photographic lens, and is conducive to the miniaturization of the photographic lens, which is conducive to the installation of mobile products, and Avoid the high manufacturing cost and technical difficulty of lens coating technology.
本發明之一目的是提供一種光學成像鏡頭，其包含至少一光學鏡片，且其中至少一光學鏡片包含至少一短波長吸收成分，藉此，可有效吸收短波長光線，而可避免光學鏡片產生劣化的問題，進而可提升光學成像鏡頭的耐用度與成像品質。此外，由於光學成像鏡頭中至少一光學鏡片本身具有吸收短波長光線的能力，光學成像鏡頭不需搭載額外的短波長吸收/濾除元件或可減少短波長吸收/濾除元件的數量，故可增加後焦空間設計自由度，使光學成像鏡頭達到更微型化效果，從而有利於搭載於行動產品。再者，本發明的短波長吸收成分是均勻混合於光學鏡片的塑膠材料中，其並非藉由鏡片鍍膜技術賦予光學鏡片吸收短波長光線的能力，故可避免鏡片鍍膜技術製造成本過高與技術難度過高的缺失。 An object of the present invention is to provide an optical imaging lens, which includes at least one optical lens, and at least one of the optical lenses includes at least one short-wavelength absorbing component, thereby effectively absorbing short-wavelength light and avoiding deterioration of the optical lens In turn, the durability and imaging quality of the optical imaging lens can be improved. In addition, since at least one optical lens in the optical imaging lens has the ability to absorb short-wavelength light, the optical imaging lens does not need to be equipped with additional short-wavelength absorption/filter elements or can reduce the number of short-wavelength absorption/filter elements. Increase the degree of freedom in the design of the back focus space, so that the optical imaging lens can achieve a more miniaturized effect, which is conducive to the installation of mobile products. Furthermore, the short-wavelength absorption component of the present invention is uniformly mixed in the plastic material of the optical lens. It does not give the optical lens the ability to absorb short-wavelength light through the lens coating technology, so it can avoid the high manufacturing cost and technology of the lens coating technology. The lack of difficulty is too high.

依據本發明再提供一種塑膠材料，用以製作前述光學成像鏡頭的光學鏡片。 According to the present invention, a plastic material is provided for manufacturing the optical lens of the aforementioned optical imaging lens.
當T3540及T4045滿足上述條件時，可有效吸 收短波長光線，並可提升光學成像鏡頭的成像品質。 When T3540 and T4045 meet the above conditions, they can effectively absorb short-wavelength light and improve the imaging quality of optical imaging lenses.
當T5058滿足上述條件時，可以避免影像的綠色偏缺陷。 When T5058 meets the above conditions, the green cast defect of the image can be avoided.
當TKmax/TKmin滿足上述條件時，可使光學成像鏡頭的成像更清晰、提成像高對比度與高潔淨度效果，進一步藉由藍光的消除可有效改善影像的紫邊缺陷，因此達到提升成像品質的功用。更能夠增加光學成像鏡頭後焦的空間設計自由度，而具有更短的後焦設計則可使光學成像鏡頭達到更佳的微型化效果。 When TKmax/TKmin meets the above conditions, the image of the optical imaging lens can be made clearer, and the effect of high contrast and high cleanliness can be improved. Further, the elimination of blue light can effectively improve the purple fringing defect of the image, so as to improve the image quality function. It can further increase the spatial design freedom of the back focus of the optical imaging lens, and a shorter back focus design can make the optical imaging lens achieve better miniaturization effects.

本發明提供一種光學成像鏡頭，由物側至像側包含至少一光學鏡片，且光學成像鏡頭的整體系統焦距為正屈折力。藉此，有效達成光線匯聚以聚焦形成影像。 The invention provides an optical imaging lens comprising at least one optical lens from the object side to the image side, and the overall system focal length of the optical imaging lens is positive refractive power. In this way, the convergence of light is effectively achieved to focus and form an image.
光學鏡片具有屈折力(可具有正屈折力或負屈折力)，其物側表面近光軸處為凸面或凹面，其像側表面近光軸處為凸面或凹面，其物側表面及像側表面中至少一表面為非球面，且光學鏡片由塑膠材料所製成。藉此，可視需求設計光學鏡片的面型，有效減少像差產生以提升成像品質，而非球面能夠滿足微型化設計需求，且選擇合適塑膠材料能夠減緩螢光問題與滿足量產目的。 Optical lens has refractive power (it can have positive refractive power or negative refractive power), its object side surface is convex or concave at the near optical axis, its image side surface is convex or concave at near optical axis, and its object side surface and image side At least one of the surfaces is aspherical, and the optical lens is made of plastic material. In this way, the surface shape of the optical lens can be designed according to the demand, which can effectively reduce the aberration and improve the image quality. The aspheric surface can meet the needs of miniaturization design, and the selection of suitable plastic materials can alleviate the fluorescent problem and meet the purpose of mass production.
光學成像鏡頭中，至少一光學鏡片包含至少一短波長吸收成分，短波長吸收成分均勻混合於塑膠材料中，包含短波長吸收成分的光學鏡片具有屈折力且其物側表面及像側表面中至少一表面為非球面。藉此，光學成像鏡頭不需搭載額外的短波長吸收/濾除元件或可減少短波長吸收/濾除元件的數量，故可增加後焦空間設計自由度，使光學成 像鏡頭達到更微型化效果，從而有利於搭載於行動產品。再者，本發明的短波長吸收成分是均勻混合於光學鏡片的塑膠材料中，其並非藉由鏡片鍍膜技術賦予光學鏡片吸收短波長光線的能力，故可避免鏡片鍍膜技術製造成本過高與技術難度過高的缺失。 In the optical imaging lens, at least one optical lens includes at least one short-wavelength absorbing component, and the short-wavelength absorbing component is uniformly mixed in the plastic material. The optical lens containing the short-wavelength absorbing component has refractive power and has at least one of the object side surface and the image side surface. One surface is aspherical. As a result, the optical imaging lens does not need to be equipped with additional short-wavelength absorbing/filtering elements or the number of short-wavelength absorbing/filtering elements can be reduced, so the design freedom of the back focus space can be increased, and the optical imaging lens can achieve a more miniaturized effect , Which is conducive to carrying mobile products. Furthermore, the short-wavelength absorption component of the present invention is uniformly mixed in the plastic material of the optical lens. It does not give the optical lens the ability to absorb short-wavelength light through the lens coating technology, so it can avoid the high manufacturing cost and technology of the lens coating technology. The lack of difficulty is too high.
包含短波長吸收成分的光學鏡片於波長350nm~400nm的平均穿透率為T3540，包含短波長吸收成分的光學鏡片於波長400nm~450nm的平均穿透率為T4045，其滿足下列條件：T3540
本發明之光學成像鏡頭中，特定波長範圍中的平均穿透率在計算時皆包含各端點的穿透率，也就是說，當計算波長350nm~400nm的平均穿透率時，是將波長350nm所對應的穿透率、波長351nm所對應的穿透率，乃至波長 400nm所對應的穿透率予以相加平均，而計算的基礎波長不以1nm為限。 In the optical imaging lens of the present invention, the average transmittance in a specific wavelength range includes the transmittance of each endpoint when calculating, that is, when calculating the average transmittance of the wavelength from 350nm to 400nm, the wavelength The transmittance corresponding to 350nm, the transmittance corresponding to the wavelength of 351nm, and even the transmittance corresponding to the wavelength of 400nm are added and averaged, and the calculated base wavelength is not limited to 1nm.
前述短波長吸收成分是指可吸收短波長光線的物質。換言之，本發明的短波長吸收成分可吸收UVB(波長範圍為280nm~315nm)及UVA(波長範圍為316nm~400nm)。藉此，可避免光學鏡片產生劣化的問題，進而可提升光學成像鏡頭的耐用度與成像品質。此外，依據本發明的短波長吸收成分可同時吸收高能量藍光(波長範圍為401nm~434nm)。藉此，可阻隔或降低高能量藍光進入光學成像鏡頭，進而可避免影像產生紫邊缺陷，可進一步提升成像品質。 The aforementioned short-wavelength absorption component refers to a substance that can absorb short-wavelength light. In other words, the short-wavelength absorption component of the present invention can absorb UVB (wavelength range of 280nm~315nm) and UVA (wavelength range of 316nm~400nm). In this way, the problem of deterioration of the optical lens can be avoided, and the durability and imaging quality of the optical imaging lens can be improved. In addition, the short-wavelength absorbing component according to the present invention can simultaneously absorb high-energy blue light (wavelength range of 401nm~434nm).

依據本發明的光學成像鏡頭，其中短波長吸收成分可為有機化合物。藉此，有助於維持光學鏡片的透明度。其中，短波長吸收成分可為苯並三唑類化合物(benzotriazole compound)。藉此，具有苯並三唑官能基的化合物有較佳的吸收能力，有助於強化280nm~400nm波長範圍的吸收效果。前述苯並三唑類化合物是指包含經取代或未經取代之苯並三唑官能基的化合物，未經取代之苯並三唑官能基的結構如式(i)所示：
依據本發明的光學成像鏡頭，其中短波長吸收成分可為2-(2'-羥基-3'-叔丁基-5'-甲基苯基)-5-氯苯並三唑(2-(2'-Hydroxy-3'-t-butyl-5'-methylphenyl)-5-chloro benzotriazole)、2-(2'-羥基-5'-叔辛基苯基)苯並三唑(2-(2'-Hydroxy-5'-t-octylphenyl)benzotriazole)、2,2'-亞甲基雙[6-(2H-苯並三唑-2-基)-4-(1,1,3,3-四甲基丁基)苯酚](2,2'-Methylenebis[6-(2H-benzotriazol-2-yl)-4-(1,1,3,3-tetramethylbutyl)phenol])、2,2'-(1,4-亞苯基)雙(4H-3,1-苯並惡嗪-4-酮)(2,2'-(1,4-Phenylene)bis(4H-3,1-benzoxazin-4-one))或其混合。也就是說，前述短波長吸收成分可單獨使用，或同時使用兩種以上。藉此，短波長吸收成分可有效吸收高能量紫外光又可避免螢光問題，由於部分塑膠材料也會因紫外光而具有螢光問題，短波長吸收成分可藉由吸收紫外光而使塑膠材料的螢光問題一併消除，螢光問題的解決有利於維持高成像品質。所述螢光干擾成像問題係指某些可吸收短波長的物質，其在吸收能量較高的紫外光後，會放出能量較低的藍光，而產生干擾成像的問題。前述2-(2'-羥基-3'-叔丁基-5'-甲基苯基)-5-氯苯並三唑的CAS(Chemical Abstracts Service)編號為3896-11-52-(2'-羥基-5'-叔辛 基苯基)苯並三唑的CAS編號為3147-75-9，2,2'-亞甲基雙[6-(2H-苯並三唑-2-基)-4-(1,1,3,3-四甲基丁基)苯酚]的CAS編號為103597-45-1，2,2'-(1,4-亞苯基)雙(4H-3,1-苯並惡嗪-4-酮)的CAS編號為18600-59-4。 According to the optical imaging lens of the present invention, the short-wavelength absorption component can be 2-(2'-hydroxy-3'-tert-butyl-5'-methylphenyl)-5-chlorobenzotriazole (2-( 2'-Hydroxy-3'-t-butyl-5'-methylphenyl)-5-chloro benzotriazole), 2-(2'-hydroxy-5'-tert-octylphenyl)benzotriazole (2-(2 '-Hydroxy-5'-t-octylphenyl)benzotriazole), 2,2'-methylenebis[6-(2H-benzotriazol-2-yl)-4-(1,1,3,3- Tetramethylbutyl)phenol](2,2'-Methylenebis[6-(2H-benzotriazol-2-yl)-4-(1,1,3,3-tetramethylbutyl)phenol]), 2,2'- (1,4-Phenylene)bis(4H-3,1-benzoxazin-4-one)(2,2'-(1,4-Phenylene)bis(4H-3,1-benzoxazin-4 -one)) or a mixture thereof. In other words, the aforementioned short-wavelength absorbing components may be used alone, or two or more of them may be used simultaneously. In this way, short-wavelength absorbing components can effectively absorb high-energy ultraviolet light and can avoid fluorescence problems. Because some plastic materials also have fluorescence problems due to ultraviolet light, short-wavelength absorbing components can make plastic materials by absorbing ultraviolet light. The problem of fluorescence is eliminated at the same time, and the solution of the problem of fluorescence is conducive to maintaining high image quality. The problem of fluorescence interference imaging refers to the problem of some substances that can absorb short wavelengths. After absorbing the ultraviolet light with higher energy, it will emit blue light with lower energy, which causes the problem of interference with imaging. The CAS (Chemical Abstracts Service) number of the aforementioned 2-(2'-hydroxy-3'-tert-butyl-5'-methylphenyl)-5-chlorobenzotriazole is 3896-11-52-(2' -Hydroxy-5'-tert-octylphenyl) benzotriazole CAS number is 3147-75-9, 2,2'-methylenebis[6-(2H-benzotriazol-2-yl) The CAS number of -4-(1,1,3,3-tetramethylbutyl)phenol] is 103597-45-1, 2,2'-(1,4-phenylene)bis(4H-3, The CAS number of 1-benzoxazine-4-one) is 18600-59-4.
